ABTICLE-DIPPING APPARATUS.

Application filed September 7, 1923. Serial No. 661,466.

This invention relates to certain new and useful improvements in articledipping machines more especially designed for coating handles or otherarticles with celluloid or other material.

In dipping articles to apply a coating of is withdrawn and to preventthe formation of runs or uneven portions thereon. Her-etofore, thearticles have been immersed in the liquid celluloid or other materialand then gradually extracted by manual means, the

' result being an uneven coating and furthermore involving considerablelabor expense.

Having the above in mind, it is the primary object of this invention toprOvide mechanical means for gradually and evenly extracting orremovingart-icles from the liquid celluloid or other material wherebythe material is applied to the article in an even film producing asmoothfinish.

It is another object of this invention to provide a mechanism for slowlyextracting or removing articles from the container of liquid celluloidor other material in which the speed of withdrawal may be readilyadjusted.

This invention has for a further object to provide a rockingly mountedframe member, one. end of which is adapted to support the article to bedipped and the other end of which is connected with a plunger, theclownward stroke of which is checked, the end of the rocking frameconnected with the plunger carrying weights whereby said end isgradually depressed against the action of the check ing means andconsequently the free end of the rocking frame and the articles carriedthereby and immersed in the container of liquid material, slowly raised.

A still further object of this invention resides in the provision of asimplified construction of slow, article dipping machine which is ofextremely simple design and construction and capable of readyinstallation at a minimum cost.

With the above and other objects in view which will appear as thedescription proceeds, my invention resides in the novel con- 'struction,combination and arrangements of parts substantially as hereinafterdescribed and more particularly defined by the ap pended claims,it beingunderstoodthat such changes in the precise embodiment of thehereindisclosed invention may be' made as come within thescope of theclaims. In the accompanying drawings, I have lllustrated one completeexample of the physical embodiment of my invention constructed accordingto the best mode I have so far devised for the practical application ofthe principles thereof, and in which:

Figure 1 is a side View of an apparatus embodying the features of myinvention;

Figure 2 is a top plan viewthereof;

I Figure 3 is a transverse sectional view taken through the mechanismfor checking the withdrawal of the articles from the celluloid or othermaterial, saidview being taken through Figure 4 on the plane of the line33;

' Figure 4; is a View partly in section and partly in elevation takenthrough Figure 3 on the plane of the line 4: 1;

Figure 5 is atop plan view of the adjust able valve memberfor'regulating the volume of fluid passing the checking member plungerduring its downward movement, and

Figure 6 is a side view thereof.

Referring now more particularly to the accompanying drawings, in whichlike numerals designate like parts throughout the several views, thenumeral 10 designates a pair of standards or supports connected attheirupper ends by a cross rod 11 which pivotally mounts a rocking frameconstructed of two spaced, side beams 12 connected attheir op positeends by cross rods 13 and.14;.

The pivot point of the rocking frame is preferably spaced agreaterdistance from the cross rod 1 1 than cross rod 13 whereby the distancetraveled by the end 14 of the frame is greater than that traveled by end13. Suspended from cross rod 14: are a plurality of hooks or rackcarrying members 15 to which a rack member 16 is adapted to besecuredand from which the articles 17 to be coated with celluloid or any othermaterial are suspended. Mounted beneath the rack carrying members 15,and adapted to receive the same when the adjacent end of the rockingframefis depressed, is a vat or container 18. filled with celluloid orother material, in a substantially liquid state, with which it isdesired to coat articles 17.

Mounted beneath end 13 of the rocking frame is a checking mechanism forslowing the descent of the adjacent end of the rocking frame andconsequently the upward move.- ment of the end 14 of the frame and thewithdrawal of the articles-17 from the mate-- rial 19. This mechanismisillustrated in. the form of a cylinder 20, one end of'which is closed bya base 21 adapted to be secured to the floor, or other support, and theother end of which is closed by a removable head or cap 22, the top ofwhich is provided with a central bore" or opening 23 through which pasesa piston rod 24. The upper end of rod 24-isformed with an eye member'25provided with an elongated slot or opening 26 through which cross rod1'3 passes.

Mounted on the end of'rod 24' within cylind'er *is a piston head 27having a plurality ofop'enings or fluid passages 28' adapted to beopened to permit the free passage of fluid by the piston in its upwardmovementand closed during the downward movement of the piston to check:or retard its return. During the descent of the piston, the fluidgradually leaks therepast through an adjustable bypass in a screw member29 threaded in an opening 30 in the pistonhead and having a passage 31therethrough, the end 32 of which is in the side of the screw above thepiston head whereby its area may be diminished or increased by screwing.member 29 thereinto or out of the piston head, respectively.

The means for closing openings 28 during the descent of the piston headconsists of a plate orvalve member 33 which is slidably mounted on astud or projection 34 extended beyond theunder side of the pistonhead,said platehaving an opening 35 therein through which the lower end ofmember 29 passes to permit the unrestricted movement of the valve memberon the stud 34. The interior of the cylinder is preferably filled withoil or any other fluid and after the articles to be clipped have beensupported from the members 15, the end 14 of therocking frame isdepressed to fully immerse the articles sup ported therefrom in thecelluloid or other material 19, this depressing. movement of the end ofthe rocking frame carrying the articles to be dipped beingunobstructedby reason of theopenings 28 being open to permit the free passagetherethrough of the oil or other fluid 1n the cylinder.

Connecting. the beams 12, intermediate pivot 11 and cross rod 13 is across rod 36, the intermediate portion of which is preferably providedwith a loop or depressed part 37 from which is suspended" a rod 38adapted to readily removably support one or more weights 39. The weights39, after the articles have been fully immersed in the material 19, tendto depress the end 13' of the rocking fiameconnected with the checkingdevice and gradually move the piston head downwardly as the fluid withinthe cylinder passes from the-underside of the piston tothe upper sidethereof through bypass 31, the articles being thus slowly withdrawn orextracted from the material at an even rate.

Upon the articles being entirely extracted or withdrawn from thematerial 19 they are removed from the members 15 and carried to adrying'room or a place of storage and the members 15 again charged witharticles to be dipped and the end 14' of the rocking frame depressedinthe manner above described.

As will be readily apparent, the speed at which the articles arewithdrawn from the material 19 may be readily regulated by either thechanging of weights 39, the adjus ment of bypass 31, or both. An opening40 is provided in the head or cap 22 which registers with member 29whereby the adjustment of the bypass may be accomplished when the pistonis at or near its upper-most position.

lVhat I claim as my invention is:
